    • Locate the rubber contact points.

    • Solder the rubber contact points, while using the spudger to pry the PCB loose.

    • PCB stands for Printed Circuit Board.

    • Toxic gasses might be created. Hence, do this in a well ventilated room.

    • Start with the lower plugs (left on the photo). Gently pry the PCB loose at the same time.

    • For this step a third person is required for safety. One person uses the solder iron, the other one uses the spudger to pry the PCB loose.

    • If you don't have accessibility to a solder iron, use a utility knife to remove the plugs.
